A pair of them recently took up residence in one of our birdhouses. http://ncmountainwoman.blogspot.com/2009/04/nuthatches-sublet-to-titmice.html)
We've been delighted to watch them with their courtship display and nest building.
Imagine our surprise when we noticed another pair of titmice investigating a decorative gourd we have hanging in the trees. The gourd is not well designed for nesting, and we never thought any bird would use it. We simply thought it attractive with its leather leaves.
At first we thought perhaps the pair in the other house had decided to move. But as we watched, we realized there were two pairs of titmice, nesting in the same (albeit large) tree.
The gourd is so close to the deck, we can hear the movements inside. What a delightful sound to hear the fluttering as the titmouse arranges the leaves and moss she has brought inside for the nest. We know the nest is almost complete. We have seen the titmouse grabbing the Golden Retriever hair we place in the trees.
